QE65 Pro Components Table
Ocean Optics permanently secures all components in the QE65 Pro at the time of manufacture. Only
Ocean Optics technicians can replace interchangeable components, where noted.
Item Name Description
1
SMA
Connector Secures the input fiber to the spectrometer. Light from the input fiber enters the
optical bench through this connector.
2 Slit
A dark piece of material containing a rectangular aperture, which is mounted directly
behind the SMA Connector. The size of the aperture regulates the amount of light
that enters the optical bench and controls spectral resolution.
You can also use the QE65 Pro without a Slit. In this configuration, the diameter of
the fiber connected to the QE65 Pro determines the size of the entrance aperture.
Only Ocean Optics technicians can change the Slit.
3 Filter
Restricts optical radiation to pre-determined wavelength regions. Light passes
through the Filter before entering the optical bench. Both bandpass and longpass
filters are available to restrict radiation to certain wavelength regions.
Only Ocean Optics technicians can change the Filter.
4
Collimating
Mirror
Focuses light entering the optical bench towards the Grating of the spectrometer.
Light enters the spectrometer, passes through the SMA Connector, Slit, and Filter,
and then reflects off the Collimating Mirror onto the Grating.
5 Grating
Diffracts light from the Collimating Mirror and directs the diffracted light onto the
Focusing Mirror. Gratings are available in different groove densities, allowing you to
specify wavelength coverage and resolution in the spectrometer.
Only Ocean Optics technicians can change the Grating.
6
Focusing
Mirror
Receives light reflected from the Grating and focuses the light onto the CCD
Detector or L2 Detector Collection Lens (depending on the spectrometer
configuration).
7
Back-
thinned
Area
Detector
with TE
Cooling
Provides 90% quantum efficiency and bins pixels in a vertical column to acquire
light form the entire height of the spectrometer’s slit image. This improves light
collection and signal-to-noise significantly. This 2D area detector is back-thinned
(back-illuminated) and does not require the detector upgrade that is normally
applied to other detectors.
Only Ocean Optics technicians can add or remove the Detector.
8
Detector
with OFLV
Filter
Eliminates second-order effects and is used with an HC-1 Grating in a 200-950 nm
wavelength system in a QE65 Pro.
